5 To connect with the TerraIndex database to retreive projects from or upload new projects, you can connect to a webservice. This webservice provides Exports and enables these export with changes to be uploaded again.
6
7 There are two steps to consider, it’s possible to request an exact projectcode export or you could request all changed projects from a timestamp. This last option is an additional Webservice call that is very easy to use. It will tell you what Project to download because they have changes since a timestamp. This Timestamp could be your last donwload moment.

22
23 As part of on-going efforts to improve performance and scalability, we have introduced a dedicated version of DataWS named DataWSExternals.  This new service should be used for external API consumers.

49 == 1. Retreive all changed project from TerraIndex ==
50
51 To retreive all changed project from the TerraIndex database since a specific timestamp, there is a webservice call you can do. This will return all project rows that have changes since the timestamp you send within the request.
52 This way you only download projects that have changes, and it will not request project that are not needed, so it won’t keep our servers busy with exports that are not necessary.
53
54 To start connecting this webservice, you should use this URL:
55 [[https:~~/~~/web.terraindex.com/DataWSExternals/ITWDataRestService_V1_0/GetProjectsJSON>>https://web.terraindex.com/DataWSExternals/ITWDataRestService_V1_0/GetProjectsJSON]]

79
80 Set the correct values for:
81
82 * (% class="mark" %)username(%%); as the username in TerraIndex
83 * (% class="mark" %)password(%%); as the username in TerraIndex
84 * (% class="mark" %)LicenseNumber(%%); as your companies license number
85 * (% class="mark" %)ApplicationCode(%%); as provided by TerraIndex to you, if not provided, request one at: service@terraindex.com
86 * (% class="mark" %)PageSize (%%)is in the example set to 30, it will return max 30 projects if possible. This can be upgraded to more records, but it will take longer.
87 * (% class="mark" %)FromDateContentLastChanged(%%); set the correct timestamp of your last call, it will return all projects that have been changed since that timestamp.
88 * (% class="mark" %)SearchFilter(%%); set a part of the projectcode in this field and it will search for projectcodes with this specific text part in it. It will add wildcars in front and at the end of the searchfilter automatically. So not needed to provide. The searchfilter will be applied on three columns: Project Code, Project Name and Project location City name.
89 * (% class="mark" %)LastRowNR(%%); fill default with zero/'0'. If your project isn’t in the first page of 30, you could use this field for lazy loading. Call the webservice with in the request the LastRowNR = 30, and you will receive project rows 31 t/m 60 (when the pagesize is 30).

265 The **PrID **can be used as **ProjectID **in the next call to get the actual project xml file export.
266
267
268 == 2. Retreive the project export from TerraIndex ==
269
270 To request the export from TerraIndex we have a SOAP webservice. This webservice is called the ExportService, and it will provide a full project in TerraIndex Format.
271 The format of the projectfile is documentated here: [[Documentation TerraIndex Export format - dsFieldProject.xsd>>Implementation documentation.Documentation TerraIndex Export format - dsFieldProject\.xsd.WebHome]]
272
273 To start connecting this webservice, you should use this URL of the Import Export Webservice:
274
275 [[https:~~/~~/web.terraindex.com/DataWSExternals/ITWImportExportService_V1_0.svc>>https://web.terraindex.com/DataWSExternals/ITWImportExportService_V1_0.svc]]
276
277 With this URL many IDE’s can create a proxy for you, just by providing the URL. Once this proxy is created, you will have a few classes looking like the call in the image below.
278
279 [[image:image-20200108-123431.png]]
280
281 The image is created with WebserviceStudio to visualise the SOAP call to send to the webservice.
282 This is the explanation of each number inside the image~:
283 1; The endpoint URL
284 2; Create the proxy based on the WSDL
285 3; Select the export call to see what it looks like
286 4; Fill the username + password of the TerraIndex user* to call the webservice with.
287 Also fill the license and the applicationCode. //(These two fields can be requested at the TerraIndex Servicedesk.)//
288 5; Fill the **ExportType **'**Export_FIELD_XML_v1_0_0**’. This export corresponds with dsFieldProject.xsd and is the best XML to connect TI with.
289 Create at least create 2 parameters as in the image. Beacause 2 parameters are needed.
290 //If JSON is prevered use: ExportType = 'Export_FIELD_JSON_v1_0_0'//
291 6; Fill the parameter with the FileName.
292 7; Fill the parameter with **projectID**. Instead of ‘ProjectID' it’s also possible to fill the parameter ‘ProjectCode'.
293 8; Send the request and wait for the reponse. In response field ‘ResultCode’ should be 'SUCCES’ when it all went OK. If not it will tell what went wrong.
294 9; The response field 'Filecontent’is filled if it went OK, and it contains XML you can serialize.
295 10; an extra parameter is added calles: **UseZipStream**. The result data is default Base64 encoded, if you add UseZipStream = true, the result string is GZIPSTREAMED Base64 encoded. **At the end of this page, we have added an class as code, to parse the base64 or ZIPStream Base64 to a normal string.**
296 *Username and password are known by each TI user and the application manager of your company can create new usernames.
